    Eye Detection Algorithm on Facial Color Images 

    Type: Conference Paper
    Author : جلال الدین نصیری; سارا خانچی; حمیدرضا پوررضا; Hamid Reza Pourreza
    Year: 2008
    Abstract:

    We present an approach t detect eyes in color images. First of all, RGB facial image is converted to YCbCr one. According to YCbCr facial image, the proposed algorithm constructs two EyaMaps, one map from luminance component (EyeMapL) and yhe other...

    True Amplitude Depth Migration with Curvelets 

    Type: Conference Paper
    Author : حمیده ثانوی; پیمان پورمقدم; Hamideh Sanavi; Peyman P. Moghaddam
    Year: 2018
    Abstract:

    In this paper, we propose a true amplitude solution to the seismic imaging problem. We derive a diagonal scaling approach in curvelet domainfor the normal operator approximation, which is based on the fact that curvelets remain approxiately...

    Comparison of hyperspectral imaging with conventional digital imaging for quality evaluation of Agaricus bisporus mushrooms. 

    Type: Journal Paper
    Author : مسعود تقی زاده; Aoife A. Gowen; Colm P. O’Donnell; Masoud Taghizadeh
    Year: 2011
    Abstract:

    The potential of hyperspectral imaging in the Vis-NIR range (400e1000 nm) for evaluating the

    quality of button mushrooms was compared to conventional RGB imaging using a digital

    colour camera. Regression models were built to correlate...

    An Application of Image Analysys to Dehydration of Osmosed Pumpkin by Hot Air Drying 

    Type: Conference Paper
    Author : M. Shafafi Zenoozian; حمیدرضا پوررضا; محمدحسین سیگاری; سیدمحمدعلی رضوی; فخری شهیدی; M. Shafafi Zenoozian; Hamid Reza Pourreza; Mohamad Hoseyn Sigari; Seyed Mohammad Ali Razavi; Fakhri Shahidi
    Year: 2007
    Abstract:

    the color image were converted to L/a/b values .Parameters related to shape (area, perimeter,

    energy) decreased during drying time. Parameters related to the texture of the image and calculated from the color co...

    Study of Gabor and Local Binary Patterns for Retinal Image Analysis
